At the end of a company drinking party, Umeyama was taken to the head office's house and was fascinated by Naho's beautiful beauty. That night, Umeyama was so excited about her sensitive response that she licked her neck. Naho, who has a stimulating pleasure in the act of being scolded, can not put up with it and gives out his body himself and makes him fry. While she was amazed that she was approaching more and more boldly, Umeyama licked her refreshing body without worrying about having a colleague.
